Flash photography-induced maculopathy
OBJECTIVE To report a flash photography-induced maculopathy. METHODS A professional photographer blinded himself accidentally and he consulted 3 days after the event with a scotoma in his dominant left eye. A unilateral acute light-induced maculopathy with hemorrhage was observed. The lesion was studied with colour photography, fluorescein and indocyanin angiography, autofluorescence imaging ...
متن کاملMobile multi-flash photography
Multi-flash (MF) photography offers a number of advantages over regular photography including removing the effects of illumination, color and texture as well as highlighting occlusion contours. Implementing MF photography on mobile devices, however, is challenging due to their restricted form factors, limited synchronization capabilities, low computational power and limited interface connectivi...
متن کاملIlluminant Spectra-based Source Separation Using Flash Photography
Real-world lighting often consists of multiple illuminants with different spectra. Separating and manipulating these illuminants in post-process is a challenging problem that requires either significant manual input or calibrated scene geometry and lighting. In this work, we leverage a flash/noflash image pair to analyze and edit scene illuminants based on their spectral differences. We derive ...
متن کاملFlash-exposure high dynamic range imaging: virtual photography and depth-compensating flash
I present a revised approach to flash-exposure high dynamic range (HDR) imaging and demonstrate two applications of this image representation. The first application enables the creation of realistic ‘virtual photographs’ for arbitrary flash-exposure settings, based on a single flash-exposure HDR image. The second application is a novel tone mapping operator for flash-exposure HDR images based o...
متن کاملComputational Photography Using a Pair of Flash/No-flash Images by Iterative Guided Filtering
In this paper, we present an iterative improvement of the guided image filter for flash/no-flash photography. The guided filter [8] utilizes a guide image to enhance a corrupted input image as similarly done in the joint bilateral filter [3, 12]. The guided filter has proved to be effective for such applications as high dynamic range compression, image matting, haze removal, and flash/no-flash ...
